Richards, who appeared on part three of the show's reunion Monday night, admitted to host Andy Cohen that she is an "alcoholic" but said now that she's completed her third stint in rehab she is "happy to be home and I feel good."

But that's something she hasn't felt in a while. "I had so much guilt and shame for my behavior and what I did and then I drank to cover the guilt and shame and make it go away," she said. "It is a vicious cycle."
